D1	Difficulty falling or staying asleep.	E6	Sleep disturbance (e.g., difficulty falling or staying asleep or restless sleep).
E	Duration of the disturbance is at least one month: Acute–when the duration of symptoms is less than three months. Chronic–when symptoms last three months or more.	F	Duration of the disturbance (criteria B, C, D, and E) is more than 1 month. “Acute” and “chronic” eliminated.
